No it's not normal, at least not to me. left you meaning? left the relationship or is he no more? I don't understand, how long has it been since your husband left you?
Okay, it depends if your relationship was deep, you love was deep then how can you so fast get over it, now either you are really very strong in getting over things or your relationship and love between wasn't strong enough, I am not sure what it is. However you yourself mentioned desperation, and let me tell you it's not good at all, I mean being desperate isn't good at all. If you have decided to move on, give yourself time, know yourself better, look at the mistakes you made in the past relationship and so on, so before going for another man, be ready prepare yourself first otherwise your next relationship will be shaky if you do something out of desperation.

I think you're system is in shock for being suddenly alone and you want to fill that need as soon as possible because it became your routine. It's normal. Your mind and body are aching for what your husband just took away. It's a bit like smoking, you need to just give yourself time and the healing will be a bit more healthy for you if you DON'T get wound up with another man, especially so quickly. You are probably not in the right mind right now to have a relationship, and it wouldn't be fair to a guy to wrangle him in and potentially form feelings for you. There are plenty of books out there on how to grieve through a separation and that's exactly what you're doing right now, grieving a loss. Here's a link to a myTake I wrote a few months ago on some things you can do to try and make yourself happy that don't include a partner just to get you through the tough time right now.
Good luck! :) You'll be okay.
